Jan Carel Josephus van Speijk (1802-31), Naval officer.

Pluckx carved the image directly into a single piece of ivory, a material prized for its smooth surface and rarity. Subtle gradations of light and shadow—an application of chiaroscuro—create a three‑dimensional effect, especially on the face, where soft shadows model the features and lend the portrait a lifelike presence.

The relief entered the Rijksmuseum’s holdings as part of its early nineteenth‑century Dutch portrait collection. Its provenance traces back to the artist’s workshop in the 1830s, reflecting the period’s interest in commemorating naval heroes through finely crafted, portable artworks.

During the post‑Napoleonic era, the Dutch navy regained prominence, and portraits of officers served both commemorative and propagandistic purposes. Ivory reliefs, though costly, were favored for their durability and the prestige they conferred, aligning with the social status of the emerging professional officer class.
